+## Guerilla infrastructure
+We are installing mobile infrastructure on a [Raspberry PI model 3](https://www.raspberrypi.com/products/raspberry-pi-3-model-b/).
+[Yunohost](https://yunohost.org/en/install) is a nice package sitting on top of [debian linux](https://www.debian.org) which simplifies system administration a lot. It installs a working web server, LDAP directory with a nice web UI for user / application administration.
+## Installation
+First we flash the install image on microsd card.
+    sudo dd if=2022-12-06-yunohost-lite.img of=/dev/sdc bs=1M && sudo sync
+Careful that you get the `of=` part right; if you miss a letter you could break your operating system's partition and lose data.
+Then we put the card in the raspberry.
+Find the raspberry's IP address.
+We connected it via a switch to a computer that runs a DHCP server (on 192.168.1.0/24).
+A nmap scan revealed the raspberry's IP address, `192.168.1.109`:
+    g1smo@dbn ~ » sudo nmap -sP 192.168.1.0/24
+    Starting Nmap 7.93 ( https://nmap.org ) at 2023-07-07 18:54 CEST
+    Nmap scan report for 192.168.1.109
+    Host is up (0.00047s latency).
+    MAC Address: B8:27:EB:F5:31:56 (Raspberry Pi Foundation)
+    Nmap scan report for dbn (192.168.1.100)
+    Host is up.
+    Nmap done: 256 IP addresses (2 hosts up) scanned in 4.27 seconds
+So we put the IP address in a web browser to finish setting up yunohost with the configuration wizard.
+### set main domain
+We registered a domain name bask.kompot.si for this occasion.
+Next we set an admin password (`letmein`).
+When the installation finishes, we go back to the IP address `192.168.1.109`, since it's not really on the internet yet.
+We use the nice web UI to create a users, `bask`, and set a password for it, `properteaistheft`.
+Next, we click on "Manage groups and permissins" on the user management page and add the "SSH" permission to the `bask` user. This way we can use SSH to log into the raspberry: `ssh bask@192.168.1.109`.
+We `su` to root and add our `bask` user to the `sudo group`, giving it administration privileges: `gpasswd -a bask sudo`.
+Then we close the terminal and login via ssh again.
+### Unblock wifi
+We unblock the wifi, running `sudo raspi-config`.
+First we set the geographical zone for wireless compliance with regulation: `1. System options > S1 Wireless LAN > SI (Slovenia)`. Or we do not do that ;) (You can also choose a random country really)
+Then we enter the SSID and password for a hotspot with internet access.
